Which type of enrollment requires a Managed Apple ID?

User Enrollment, designed for BYOD, requires a Managed Apple ID to separate personal and managed data on the device. The Managed Apple ID authenticates the user for organizational policies while preserving personal privacy. Automated Device Enrollment (option A) and Device Enrollment (option B) are for organization-owned devices and don’t inherently require Managed Apple IDs, though they can use them optionally. TheApple Platform Deployment Guidespecifies that User Enrollment relies on Managed Apple IDs for its functionality.
